according to ledgrowlightmanafactureuk,the ir should be visible,gonna try there product,check out there products via ebay,led got me going crazy,,lol
Infra Red should be visible? Its Not IR then mate, IR is invisible to the naked eye after 750Nm, therefor any clam that a visible Red LED is IR is not True IR its far red,
,,,
NASA proved it with their in space growth testing, so have the Russians, and oh wait....China.
The Eden project uses IR only for two hours after lights off tho,
Any light Red will clash and have a negative effect on IR aswell so mixing 610, 630,650 Nm with IR is no good in my opinion. Same as the Blue,
All LED companys arnt using the right NM, that's all im gonna say,,,apart from
watch this space as I am introducing my OWN spectrum to my test lights soon,
Cant wait.
As I have always said "the proof is in the testing"
